I picked this serum because i could still use hyloranic acid products without worrying about them interacting and its so good!! It faded my acne scars so well which is a feat considering how sensitive my skin is.
I don't apply it as frequently as recommended. So I haven't noticed a significant improvement in the small pigmentation areas. However, the most important thing for me is that the serum did not irritate my skin at all. It was gentle and well-tolerated.
